LOUIS G. GRADY, OF HALIFAX, NORTH CAROLINA.

TOOL FOR JEWELERS USE.

SPECIFICATION forming part of Letters Patent No. 234,560, dated November16, 1880.

Application filed August 2, 1880. (Model.)

To all whom it may concern:

Be it known that I, LOUIS G. GRADY, of Halifax, in the county of Halifaxand State of North Carolina, have invented a new and Improved Tool forJewelers Use, of which the following is a specification.

The object of my invention is to furnish a tool for holding smallarticles or pieces ofjewelry while being soldered, so as to dispensewith binding-wire, plaster-of-paris, and the various inconvenient,troublesome, and dirty contrivances hithertofore used in such work.

My invention consists in a bar or plate provided with articulated armsthat carry tweez ers, the parts being so constructed and arranged thatthearticles or parts can be placed in the tweezers and brought togetherand held in any required position for being soldered.

My invention is shown in the accompanying drawings, wherein Figure l isa perspective view of the tool as applied to use. Fig. 2 is a side viewof the same in a closed position.

Similar letters of reference indicate corresponding parts.

A is a bar or plate of metal, of convenient length, and sufficientlythick to prevent bending while being handled. Instead of the long andnarrow bar shown, it may be a plate of triangular or quadrangular form.

To the ends of bar A the arms B B are jointed. These arms are eachcomposed of two or more jointed sections, I), that consist of curvedmetal plates attached together and to bar A by rivets that permitmovement at the joints. with spring-washers to impart sufficientfriction for holding the parts in place as turned.

To the end of each arm B is jointed a pair of spring-tweezers, a, whichare provided with rings, screws, or other devices by which the articlecan be clamped. By this construction the articles or pieces to besoldered together may be secured in the tweezers and the pieces broughttogether in the proper relative position for soldering, in whichposition they will be held whilethe tool is held in onehand of theoperator.

The tool is adapted for use in soldering the various shaped articles,and for all the exigencies of jewelry-work. By its use much time, labor,and annoyance will be saved and better work accomplished.

The tool may have three or four arms B, instead of two, as shown, inwhich case the arms will be attached to the angles of the triangular orquadrangular plate A before mentioned.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The tool for jewelers use consisting of bar or plate A, provided witharticulated arms B, carrying tweezers a, substantially as shown anddescribed.

LOUIS G. GRADY.
